Greensboro, NC -- Sometimes you don't want to talk on a flight, but you end up next to someone who wants to chat.

Body language expert, Blanca Cobb explains how to send the message that you don't want to talk without being rude.

"Silent messages are powerful. You start by politely saying excuse me, you do not look at the person who you're crossing over. You sit in your seat," Cobb said. "You can start looking through your bag, or your briefcase for a few seconds, then put your items where they belong below the seat in front of it, and continue to look straight."

She also added: do not look at anyone no matter how much they're staring.
